For me it’s the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they’re being spied. Here’s the secret - unplug the damn thing when you think you won’t use it or haven’t used it in a while.
They, whoever it is, can’t really spy on you on something that’s already off and unplugged!

I’ve never heard anything like this.
It appears I either misunderstood or misremembered what I read.
It probably referred to MAC addresses being reused on WiFi. However the frames used are not Ethernet frames.
Ethernet however is not restricted to twisted pair cat cables it’s on fiber and originally was on co-axial.
